/**
 * EIP-55 address helpers for the agentsmarket CLI.
 *
 * Two forms matter:
 *   - Checksum (display): mixed case from EIP-55 — `0xC02aaE36...`
 *   - Lowercase (internal/comparison): `0xc02aae36...`
 *
 * Convention:
 *   - Storage (config.json, D1, in-memory comparisons) = lowercase
 *   - Display (`agentsmarket info`, server JSON responses, log lines) = checksum
 *
 * ethers' Wallet/HDNodeWallet already returns checksum addresses on creation
 * and verification, so `init` and signature flows produce checksum strings
 * naturally. This module normalizes anything that crosses a boundary to
 * prevent "0xAbC vs 0xabc" mismatches.
